Graphene-Based Artificial Retina Sensor Being Developed
Researchers at Germany’s Technical University of Munich are developing graphene sensors like the ones depicted above to serve as artificial retinas. The atom-thick sheet of linked carbon atoms is being used because it is thin, flexible, stronger than steel, transparent and electrically conductive.
TUM physicists think that all of these characteristics and graphene’s compatibility with the body make it a strong contender to serve as the interface between a retinal prosthetic that converts light to electric impulses and the optic nerve. A graphene-based sensor could help blind people with healthy nerve tissue see, they say.
Exactly 45 years ago today, after months of preparation, Apollo 11 embarked on its now-legendary mission to the moon. But what exactly does it take to send three men into the great, vacuous unknown? See for yourself.
This 353-page document is the entire Apollo 11 flight plan in all its scientific glory. And if it gets a little confusing it’s because this is one of those rare cases where, yes, it actually is rocket science.
- CSM = Command Service Module
- CMP = Command Module Pilot (Mike Collins)
- LM = Lunar Module
- CDR = Commander of the Mission (Neil Armstrong)
- LMP = Lunar Module Pilot (Buzz Aldrin)
- MCC-H = Mission Control Center-Houston.
- LLM = Lunar Landing Mision
- S/C = Spacecraft
And as an added bonus, NASA has also kindly made available the entire Apollo 11 onboard voice transcription. Yep—you get to be privy to every last word uttered between our three space heroes as they were making history happen.

First I chant a little, then I do this double-jointed thing with my shoulder blades & then the posts materialize from Heaven, right into my drafts; & if I’d been very good that day they come already captioned & tagged for me.
(Each post is linked to its source, the art is all over the world-wide webbyweb for our downloading pleasure.)
Sorry, I haven’t slept.
ahaha right on point
